This report presents analysis of a database of global geothermal drilling success. The database, compiled by IFC, covers geothermal fields that together supply power to 71 percent of the world's installed geothermal electricity generating capacity, making it the largest database of its kind.
... See More + This report analyzes that data to gain a better understanding of the probability of drilling a successful well, and the factors that influence such success, which will be of interest to geothermal developers, and to financers engaged in the risk assessment of such projects. The core objective of this project was to develop a sufficiently large database to allow statistically significant conclusions to be drawn on the success rates of geothermal wells worldwide (expressed as the number of successful wells developed as a proportion of total wells drilled in any given field). This report seeks to assess the extent of any improvements in well success rates, and how far the likelihood of success increases as a developer learns more about any specific resource.
